Fabric



C. E. PINK FABRIC Filed Jan. 15, 1934 Feb. 26, 1935.

Patented Feb. 26, 1935 UNITED STATES PATENT oFFIcE 2 Claims.

This invention relates to fabrics of the coil woven type somewhat similar to that set forth in my U. S. Letters Patent granted February 13, 1934, and numbered 1,947,357, and has for the primary object the provision of a fabric of the above stated character which will be durable and have maximum strength and flexibility and consists of three or more superimposed layers, each layer composed of coiled strands woven one into another with their ends connected or secured together and the convolutions of a pair of layers nested into each other and the coiled strands of another or third layer retaining or securing the coiled strands of said pair of layers in nested relation and still permitting each layer to have flexibility.

With these and other objects in view this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary plan view illustrating an incompleted fabric composed of three superimposed layers and constructed in accordance with my invention.

Figure 2 is a fragmentary plan View illustrating one 'of the layers of the fabric and consisting of right hand coil strands.

Figure 3 is a similar view illustrating a second layer of the fabric and consisting of left hand coil strands.

Figure 4 is a similar view illustrating a third layer of the fabric and consisting of right hand coil strands.

Figure 5 is a sectional view taken on the line 5 5 of Figure l.

Referring in detail to the drawing, the fabric 1 is constructed of layers 2, 3 and 4 arranged in superimposed relation and the layers 2 and 4 are composed of right hand coil strands and the layer 3 is composed of left hand coil strands. The strands of each layer have the ends thereof secured together, as shown at 5, after the assembling of the layers in fabric formation and which will be hereinafter more fully described.

The layers 2 and 3 are constructed or assembled in the usual manner so as to provide independent units and said layers are brought together in superimposed relation so that the coil strands thereof nest one within the other as disclosed in the right hand portion of Figure 1. The coil strands which go to construct the layer 4 in the finished fabric are then fed or spiraled into the coiled strands of the layer 2 one at a time and also fed one into another. The strands of the layers 2 and 4 being ofright hand coils permit the above to be accomplished. As the strands of the layer 4 are fed into the strands of the layer 2 and into each other they pass over thestrands of the layer 3 so that the latter-named layer will be retained nested in the layer 2 and be prevented from separating therefrom. It is to be understood that the strands which hold the layers 2 and 3 in nested relation form in themselves a complete layer. The assembly described has maximum strength and durability and each layer thereof has flexibility so that the fabric when employed in conveyor belts and similar devices will be capable of withstanding excess strains and loads and will readily travel over curved surfaces such'as supporting and driving drums or pulleys.

While the fabric constituting the present invention has been described and illustrated as composed of three layers it is to be understood that the number of layers may be increased and secured together in the same manner.

Having described the invention, I claim:

l. A fabric comprising layers each embodying interwoven strands, the strands of one layer being of right hand coiled formation and the strands of the other layer being of left hand coiled formation, and coiled strands having the same formation as the strands of one of said layers and interwoven therewith from the opposite side of the other layer to hold said layers against separation.

2. A fabric comprising layers each embodying interwoven strands, one of said layers having the strands thereof of right hand coiled formation and the other layer having the strands thereof of left hand coiled formation, and coiled strands having the same formation as the strands of one of said layers and `interwoven therewith from the opposite side of the other layer and interwoven with each other to form a third layer for connecting and reinforcing said first layers.
